To all whom it may concern. i

Beit known that I, WILLIA HARRY Run,

a citizen of the United States, residingin Rosell Park, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Wireless Detectors, of which the following is a full,

v clear, and concise description. c

. :My invention relates towireless detectors myjmore particular purpose being to give a the detector such form that durin'g its active use it may be readily vcarried around upon the person without causing inconvenience tothe individual carrying it, and also to confer upon, the detectorfa high degreeof sensi tiveness and togive the operator a special and immediate control over its sensitiveness,

not generally attained inthe use of a wire;

less detector.

Reference is made 'to the accompanying 1: drawing'forming a part of thls specification,

and inwhich like reference characters indicate like parts throughout the several figures.

the figure being mainly an elevation, one of the partsbeing shown partlyin section.

nism appearing in Figure 1, and shows the magnetic wavesof great, length. I V V Figure 3 is an edgeview of the mechan sm shown in Figure 2.

Figure 4 is a. plan view of the detector shown in Figures 1 to 3 inclusive, and illustrates how the detector is mounted upon and carried by the operators finger.

Figure 5 is a side elevation of another form of my invention adapted in thisinstance for use as a scarf pin.- V

' and the crown setting 10 being similarly provided with fingers 12. V

Fitted neatly into the crownsetting 9 and held firmly by'the fingers 11 thereof is a block 13, having a substantially cubical form and'madeof insulating material, such as hard rubbertorbakelite-i carries a metallic stem 14, having-substan- I tially the form of an invertedL, and provided with an eye 15, adapted for use asa binding post, The stem 14 supports: a 'whiskerlo, having theYYform' of a helical Y winding of wire provided with a1 point '17 The, whisker-stem 1 4: by means of-lthe, block 13 insulated'from the crown setting 9 and. metallic parts immediatelyconn t d therewith; r

block .18, upon whic'h the point 117 [restslightly.

r The crownsetting carries a 1: extendmgupwardlyfrom it and terminat ingin, an eye 2O,servingthe"purpose offa17' binding post.

An inductancewinding if desired, as indicated in Figure 2 (This winding, when'used, is "locatedwithi'n the,

slots onewhich appears at7,i'n Figure 1..- The winding 21 is-for thepurpose-of adding. inductance, in:order-tol adapt'the detector for use in. connectionwith waves of;great length. I do not showthe electric conne 1 tionsfor therwinding 21,;or for. the other Figure 2 is aside elevation of the.mecha-,

parts, as they constitute no partsof my in-' vention.

The detector as whole fitted upon operators finger 22," and is worn somewhat after the manner of a fingerring. v

The, operator by. sliding the de tctbi- 1 lengthwise ofthe finger, .or,even by ben d-' ing this'finger, maycause the portions 8, 8,v

of the device to be forced slightly further apart or -brought a little more closely to-,

gether, :so' as .to "shift the'jposition. offlthe adjacent face of 'thejcrystal 18.1,

1 point 17 of the whisker 16, relatively'tothe I The operator, by grasping the whisker stem .14 and turning the same ,sli'ghtlyupon the block 13 as a center, can shift the whisker point 17 in the-directionfindicated' by the broken line of arcu'ate form shown in Figure l 4. Thusthe operator is enabled to bring the whisker point into contact with any portion of the adj acent face of the crystal 18.. I-Such:

being the case, it isanfeasyniatter for the i operator to make a very fine adjustment of the point 17 relatively! to the crystal. -Inthis connection I call' attention to} the fact-5' that the operator, .byver'ysli-ght muscular movements due to sliding the detector upon his finger orrby bending his finger asthefcase.

imay pail Shift? h point 17 very sligh ly results. If, for instance,'the operator finds that by! .bending hisfinger beyond a certain limit the efficiency of the-reception is impaired, but by bending his finger-up to the hlimit just mentioned the efficiency of the reception is improved, he bends his finger justffar'enough to get thebbest effect; and

then if, after another'moment, he findsthat straightening the finger out improves the effect, he straightens his finger gradually until the detector works at its best. If the detector works very badly'owing to the point 17 being in en agement with aportion of the crystal not 811%Cl611tlYSGI1SltlV6, the operator 2 can bendor straighten his finger abruptly, or

's'lidethedetector along the finger, thus displacing-the point 17 slightly upon the surf face of the crystal. Again, the operator'can grasp' the whisker stem 14, and by! turning it {slightly as indicated in Figure 4, shift it so V natural or' artificial.

that the point 17 isbrought into a more favorable position relatively to the crystal.

By practice the eye 15' is connected with antenna of any appropriate kind, and the eye 20 is connected with a ground, either This antenna and ground are' preferably portable; that is carried around by thejoper ator, and may be of any de's'ired form suitable for this purpose. Apair of head telephones are bridged across from the eye-15 to the eye 20. I do] not show these connections as they form no part of my'invention. I r

1n the'form of my device shown in Figure 5 the detector is'mounted upon a pin, suitable for use as a necktie pin or as a scarfpin.

A pin-"body 22 carries a slide 23', fitting upon it detachab-ly but rather tightly, and

providedwith an'eye 24: The operator removes the" slide 23, thruststhe pin through the necktie or scarf, and replaces the slide 23.

The slide 23 has a tendency to prevent the pm from being removedsurreptitiously by any other person. The eye 24 serves the purpose of, a binding post, or at least as one of the terminalsof the detector. g I

The pin 22 carries a crown setting 25 consisting of a metallic cylinder and provided with upwardly extending metallic fingers 26. .'These fingers encompass and hold a crystal 27.

- The crown setting 25 carries a 28 made of insulating material, preferably glass, this stem carrying an enlarged portion 29 fashioned into a bulb or globe. Mounted upon the enlarged portion 29 is a metallic cage 30, carrying a stem 31 extending upwardly Tfromit; This stem is provided with by thejoperator who wears the pin.

aneye 32, serving as a terminal ofthe detector, or practically speaking, as a binding post. The stem 31 carries a whisker 33havi-ng a helical form and provided with a point and ground being preferably carried around My device is specially adapted for use in relations where the operator maywish to; carry his receiving apparatus with him, and

observed while receivingwireless signals.

1n some relations is useful 'for enabling, an I 1 operator to remainas far as practicable unf- '1 The apparatus is well adapted for certain kinds of service inthe army or navy or by;

a police department or a detective bureau. 1 Its main mission, however, is for use as a novelty, and especially by amateurs interested in the nals.
